How to run webtests from a TFS build using powershell script - azure

Question

I have a requirement to run webtests which are located in a particular folder through a build. Currently the tests are run from Visual Studio 2015.
Got to know to execute/use the below powershell script as a task. But clueless how to implement it. Is this powershell script enough?.
param
(
$tool = "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\MSTest.exe",
$path ,
$include = "*.webtest"
)
$web_tests = get-ChildItem -Path $paths -Recurse -Include $include
foreach ($item in $web_tests) {
$args += "/TestContainer:$item"
}
In this, how to pass in the $path value? Do I need to give the path of the directory which has all these 5 webtests?
Do I need a testsettings file to carry out this execution.
If I need a test settings file, do I need to copy all the webtests file to output directory?
All I get with this powershell is the below message
No test runs are available for this build. Enable automated tests in
your build definition by adding a task that runs tests for your test
framework of choice, such as the Visual Studio Test task. If you choose
to run tests using a custom task or runner, you can publish results
using the Publish Test Results task
Could any one please help me as in what I am missing here? Thanks for your time and help on this.

how to pass in the $path value?
When you use the powershell task to execute your powershell scripts, there is a option Arguments, which you could pass the value of $path:
Do I need to give the path of the directory which has all these 5
webtests?
Yes. In general, the .webtests file are all copied to the drops location, so the path always point to the drops location.
Do I need a testsettings file to carry out this execution.
The short answer is yes.
There is a great blog about how to Running WebTests as part of a VSTS VNext Release pipeline, you can check if it helps.
Hope this helps.
